TO AIlL WHOM IT MAY -CONCERN:

Be it known that I, GARDNER. WARREN, of Roxbury, in the county of Sud'olk, and State of Massachusetts, have invented a new Process for Treating Fabrics Madelfrom Wool, Silk, and other Animal Fibres; and I do hereby declare the following to be a correct description of the same. I

The nature of my invention -consists in treating such fabrics with a solution of glycerine, in a manner to be hereafter'described, for the following purposes mainly, to wit: First, 'to increase their weightysecond, to

impart an increased firmness to the texture of the fabrics; third, to add an enduring softness and otherwise improved finish to the same. p

' For the purpose of illustrating one practicable form of making use of my invention, I will proceed to describe the same.

Taking one part of glycerine, I add thereto eight parts of water, having provided a suitable vat to hold the liquor so formed, wherein the fabrics tobe treated may be placed for a time suflicientto allow of their being perfectly saturated with said solution" or liquor, after which they are passcd'through one or more sets of pressure-rollers, or other suitable device, for the purpose of removing as much of the liquor as may ,be practicable in any given case; and, after this operation has been accomplished, said fabrics may be placed in' a dryin room, or passed through a pressing-machine, in a manner to accomplish the double purpose ofpreven'ting any shrinking or cockling, the latter process being varied to suit given'cases, readilv understood by all persons skilled in the art of such fabrications.

In given cases, I increase or diminish the proportion of the glycerine, governed by the extent of the increased weight or firmness that is desired to be given to the fabric treated. V

Other ingredients may be added to such a solution, such as alum, borax, or other similar, salts, with more or less advantage, according to the nature of the fabric treated, and for the purpose of protecting the fabric from insects, and in some cases it would be practicable to use the glyceriue independent of any other agent.

What I claim,and.desire to secure by Letters Patent, is- The process of treating fabrics, made of wool, silk, or other animal fibres, with a solution of glycol-inc, substantially as described.
